Free compliance tools
Three free tools that run in the browser with no sign-in: a HAV (hand-arm vibration) exposure calculator, a 6x6 risk-matrix calculator, and a 'what accreditation do I need?' checker. Guidance only - they make nobody compliant.
Available now. Free, with no sign-in — the tools run entirely in your browser and nothing is sent anywhere. Where each of our products stands is stated plainly.
Three tools
Small, self-contained calculators for construction and field trades. Each runs in the browser with no account and keeps nothing.
Risk-matrix calculator
A 6×6 likelihood-by-severity matrix, for putting a consistent number against a risk while you assess it.
"What accreditation do I need?" checker
A quick walk through the common construction accreditations to point you at the ones that tend to apply to work like yours — a starting point, not an answer.
Nothing to sign up to
Open the page and use them. No account, nothing sent anywhere, nothing kept.
What they are not
Guidance only
They make nobody compliant and they are not a substitute for a competent person's assessment. A calculator is a way of thinking a problem through, not a determination that the problem is solved.
They keep nothing
Everything happens in your browser. Nothing you type is sent to us or stored anywhere, which is also why there is no account to make.
